Food for all? Wildfire ash fuels growth of diverse eukaryotic plankton.

In December 2017, one of the largest wildfires in California history, the Thomas Fire, created a large smoke and ash plume that extended over the northeastern Pacific Ocean. Here, we explore the impact of Thomas Fire ash deposition on seawater chemistry and the growth and composition of natural microbial communities. Experiments conducted in coastal California waters during the Thomas Fire revealed that leaching of ash in seawater resulted in significant additions of dissolved nutrients including inorganic nitrogen (nitrate, nitrite and ammonium), silicic acid, metals (iron, nickel, cobalt and copper), organic nitrogen and organic carbon. After exposure to ash leachate at high (0.25 g ash l-1) and low (0.08 g ash l-1) concentrations for 4 days, natural microbial communities had 59-154% higher particulate organic carbon concentrations than communities without ash leachate additions. Additionally, a diverse assemblage of eukaryotic microbes (protists) responded to the ash leachate with taxa from 11 different taxonomic divisions increasing in relative abundance compared with control treatments. Our results suggest that large fire events can be important atmospheric sources of nutrients (particularly nitrogen) to coastal marine systems, where, through leaching of various nutrients, ash may act as a 'food for all' in protist communities.

Preparing for hybrid warfare and cyberattacks on health services' digital infrastructure: What nurse managers need to know.

AIM: This article aims to outline the key concepts in hybrid warfare and cyberattack to better inform nurse managers in their strategic contribution to the defence of critical digital infrastructure. BACKGROUND: Hybrid warfare often targets a nation's critical digital infrastructure including that of health services. Hybrid warfare against national health services, primarily through cyberattack, is likely to increase in a more destabilized and conflictual international environment. EVALUATION: Key literature, reports and assessments on hybrid warfare, advanced persistent threats and cyberattack referenced to health services were analysed. KEY ISSUE: Health services are a key element of a nation's critical digital infrastructure and as such are a strategic target in hybrid warfare. Cyberattack through exploiting clinicians', such as nurses, online susceptibilities is a key route of attack. Nurse managers, to be effective planners, need to be fully informed about the context and specific nature of cyberattack. CONCLUSION(S): Articles about the relationship between hybrid warfare and cyberattack on health services digital infrastructure are rarely aimed at nurse managers. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers need to be fully informed about the geopolitical nature of cyberattacks if they are to be fully consulted and listened to in response planning in defence of health services' digital infrastructure.

Exploring user empowerment and service improvement within an Irish epilepsy service using Checkland's 'Soft Systems' approach.

AIM: To illustrate the value of Checkland's 'Soft Systems' approach to explore and analyse the interaction of human and organisational factors that affect service delivery and patient experience in one specialist epilepsy service. BACKGROUND: Checkland's approach is underutilized in relation to health service improvement. One epilepsy service in Ireland is used as an example to illustrate the value of his approach to improve service delivery, particularly when what needs to change is not clear. METHOD: Checkland's 'Soft Systems' seven-stage approach was used collaboratively to explore patients' and clinicians' experience of service delivery and how to improve it. RESULTS: The research identified the practice of empowerment affected the quality of the service experience. Checkland's concept of a human activity system was particularly pertinent in identifying this issue and providing a 'map' for change. CONCLUSION: Wider inferences for the use of Checkland's approach by nurse managers are discussed, as is the value of using Checkland's approach to improve services. IMPLICATIONS FOR NURSING MANAGEMENT: Checkland's 'Soft Systems' is an underutilized approach in health care that could be used by managers to initiate and embed change within a health care service.

Conceptualizing skill mix in nursing and health care: An analysis.

AIM: This paper aims to unpack the concept of "skill mix" into its constituent parts to achieve a better understanding and reduce confusion associated with the term. BACKGROUND: Skill mix is a topic that is widely debated and is foremost on the health policy agenda due to specific local pressures within international health services. At present, however, there is large variation in terms of what is understood by the concept of "skill mix" and there is a paucity of research that attempts to analyse this concept. EVALUATION: Using Rodgers' evolutionary method of concept analysis, this paper provides an analysis of definitions of skill mix, its attributes and associated terms in the literature. KEY ISSUE: Definitions of skill mix are often vague and ambiguous and may refer to one or more attributes of skill mix. CONCLUSION: A lack of understanding of the concept can lead to an ad hoc interpretation of policy recommendations related to skill mix at local level. IMPLICATIONS FOR NURSING MANAGEMENT: A better understanding of the concept of "skill mix" and its attributes can assist both policy makers and stakeholders, including nurse management, to ensure that the potential of skill mix is maximized.

Reported implementation lessons from a national quality improvement initiative; Productive Ward: Releasing Time to Care™. A qualitative, ward-based team perspective.

AIM: To explore the experiences of participants involved in the implementation of the Productive Ward: Releasing Time to Care™ initiative in Ireland, identifying key implementation lessons. BACKGROUND: A large-scale quality improvement programme Productive Ward: Releasing Time to Care™ was introduced nationwide into Ireland in 2011. We captured accounts from ward-based teams in an implementation phase during 2013-14 to explore their experiences. METHODS: Semi-structured, in-depth interviews with a purposive sample of 24 members of ward-based teams from nine sites involved in the second national phase of the initiative were conducted. Interviews were analysed and coded under themes, using a seven-stage iterative process. RESULTS: The predominant theme identified was associated with the implementation and management of the initiative and included: project management; training; preparation; information and communication; and participant's negative experiences. The most prominent challenge reported related to other competing clinical priorities. CONCLUSIONS: Despite the structured approach of Productive Ward: Releasing Time to Care™, it appears that overstretched and busy clinical environments struggle to provide the right climate and context for ward-based teams to engage and interact actively with quality improvement tools, methods and activities. IMPLICATIONS FOR NURSING MANAGEMENT: Findings highlight five key aspects of implementation and management that will help facilitate successful adoption of large-scale, ward-based quality improvement programmes such as Productive Ward: Releasing Time to Care™. Utilising pre-existing implementation or quality frameworks to assess each ward/unit for 'readiness' prior to commencing a quality improvement intervention such as Productive Ward: Releasing Time to Care™ should be considered.

The social space of empowerment within epilepsy services: The map is not the terrain.

Empowerment is now seen as an integral component of holistic practice and service design in healthcare, particularly as it relates to the improvement of quality of life for people with epilepsy. However, the literature suggests that empowerment is a neglected and poorly understood concept by service users and providers alike within epilepsy services. Conceptual ambiguity is a further impediment to its understanding and implementation. Bearing this in mind, a clear definition of empowerment is needed in order to realistically recognize, encourage, and prioritize empowerment as a service design philosophy. Therefore, this paper undertakes a concept analysis of empowerment with reference to epilepsy services. Results indicate that empowerment demands a transformation of consciousness and a readiness to act on this transformation in order to allow people to gain personal power and autonomy over their own life, including the self-management of their condition. With this in mind, a critical reflection on the 'micro' and 'macro' levels of power that exist within epilepsy services is warranted with reference to theoretical principles. In this context although the map is not the terrain, we argue that an educational intervention guided by critical social theory principles has the potential to encourage an understanding of empowerment and 'holds the key' to future advances for its implementation within epilepsy services.

The potential of critical social theory as an educational framework for people with epilepsy.

Effective education can support people with epilepsy to develop the attributes and skills required to function as equal partners with clinical service providers, make informed decisions, and competently self-manage their healthcare. However, despite knowledge deficits, unmet information needs, and a poor sense of empowerment, the study of education for people with epilepsy is often neglected and is a poorly understood component of holistic practice within epilepsy healthcare. Historically, the only debate with regard to education and people with epilepsy has been guided either within a positivist or within a constructivist philosophy. We argue that new pedagogies are warranted, recognizing the views of people with epilepsy regarding their illness. Therefore, this paper explores the potential of an educational framework for people with epilepsy based upon critical social theory (CST). By utilizing a CST approach for education, people with epilepsy are engaged with as active 'participants'. This is a key difference that distinguishes CST from other metatheoretical frameworks. It has the potential to support people with epilepsy to acquire the skills and confidence to manage the biopsychosocial challenges associated with their condition.

British Icons and Catholic perfidy--Anglo-Saxon historiography and the battle for Crimean War nursing.

Taking as its starting point Carr's view that historical narrative reflects the preoccupations of the time in which it is written and Foucault's concept of consensual historical discourse as the outcome of a social struggle in which the victor suppresses or at least diminishes contrary versions of historical events in favour of their own, this paper traces and discusses the historical narrative of British nursing in the Crimean war and, in particular, three competing narratives that have arisen in the latter half of the 20th century and the first decade of the 21st. These are the established narrative surrounding Florence Nightingale, the new narrative surrounding Mary Seacole and an Irish narrative surrounding the role of the Sisters of Mercy. It is argued that the increased vehemence of the debate surrounding these narratives is representative of the changes that have taken place in British society. However, we also argue that the Irish narrative and its critique are reflective of deep-rooted Anglo-Protestant attitudes articulated by Nightingale and uncritically accepted by subsequent historians even in modern British historiography.

The transition of a large-scale quality improvement initiative: a bibliometric analysis of the Productive Ward: Releasing Time to Care programme.

AIMS AND OBJECTIVES: To examine the literature related to a large-scale quality improvement initiative, the 'Productive Ward: Releasing Time to Care', providing a bibliometric profile that tracks the level of interest and scale of roll-out and adoption, discussing the implications for sustainability. BACKGROUND: Productive Ward: Releasing Time to Care (aka Productive Ward) is probably one of the most ambitious quality improvement efforts engaged by the UK-NHS. Politically and financially supported, its main driver was the NHS Institute for Innovation and Improvement. The NHS institute closed in early 2013 leaving a void of resources, knowledge and expertise. UK roll-out of the initiative is well established and has arguably peaked. International interest in the initiative however continues to develop. METHODS: A comprehensive literature review was undertaken to identify the literature related to the Productive Ward and its implementation (January 2006-June 2013). A bibliometric analysis examined/reviewed the trends and identified/measured interest, spread and uptake. RESULTS: Overall distribution patterns identify a declining trend of interest, with reduced numbers of grey literature and evaluation publications. However, detailed examination of the data shows no reduction in peer-reviewed outputs. There is some evidence that international uptake of the initiative continues to generate publications and create interest. CONCLUSIONS: Sustaining this initiative in the UK will require re-energising, a new focus and financing. The transition period created by the closure of its creator may well contribute to further reduced levels of interest and publication outputs in the UK. However, international implementation, evaluation and associated publications could serve to attract professional/academic interest in this well-established, positively reported, quality improvement initiative. RELEVANCE TO CLINICAL PRACTICE: This paper provides nurses and ward teams involved in quality improvement programmes with a detailed, current-state, examination and analysis of the Productive Ward literature, highlighting the bibliometric patterns of this large-scale, international, quality improvement programme. It serves to disseminate updated publication information to those in clinical practice who are involved in Productive Ward or a similar quality improvement initiative.

Towards a gendered perspective for Irish mental health policy and service provision.

BACKGROUND: The Irish Government has adopted "Gender Mainstreaming" as a strategy to promote equal opportunities between women and men in its National Development Plan. While current mental health policy addresses the principle of partnership and social inclusiveness as a way forward for mental health service provision, it still does not explicitly deal with the notion of gender and gender sensitivity. Indeed, Irish mental health policy and service provision is criticised for being gender-neutral. AIM: This paper explores the relationship between gender, mental health policy and service provision. METHOD: The literature on theoretical perspectives on mental health policy, gender and mental health in relation to Irish mental health policy is reviewed. RESULTS: The importance of gender for policy development and service provision is recognised, and the need to reformulate debate within a gendered context is discussed. Some key theoretical perspectives and their significance for mental health policy are considered with possible explanations for the absence of a gender perspective for Irish mental health policy presented. CONCLUSION: Arguably, a move towards developing gender-sensitive mental health policy and service provision requires a stronger awareness of and connections between the macro, meso and micro levels for policy development and analysis.

Medical colleges admission test in Punjab, Pakistan.

BACKGROUND: Nearly 18,000 candidates securing 60% and above marks in Higher Secondary School Certificate (HSSC) examination contest for admission in Medical Colleges, in Punjab, Pakistan by sitting in the Medical College Admission Test (MCAT) each summer. This cross-sectional study was conducted to identify patterns related to demographic, economic and educational backgrounds, over a two-year-period, in this population, and how HSSC and MCAT marks predict future performance of the selected candidates. METHODS: Marks obtained by candidates in HSSC, MCAT, and 1st Professional MBBS (Part-I) Examinations over two years 2008-2009, were analysed using parametric tests in SPSS. RESULTS: Total 18,090 candidates in 2008 and 18,486 in 2009 sat in the MCAT. National IHSSC candidates scored higher marks in HSSC and MCAT but lower marks than their foreign qualified HSSC counterparts (e.g., Advanced-levels from Cambridge University, UK) in Part-I overall and in all its subcomponents individually (p < 0.05). Female students scored higher marks than males in HSSC (p > 0.05). MCAT (p > 0.05) and Part-I theory, practical, viva voce, continuous assessment and Objective-Structured Performance Evaluation (OSPE) components (p < 0.05). In both years, students from the Dera Ghazi Khan District scored the highest marks in the HSSC Examinations (p < 0.05) but least marks in MCAT in 2008 (p < 0.05) and in Part-I in 2008 and 2009 (p < 0.05). Students from 'tougher' Boards like Rawalpindi in 2008 and the Federal Board in 2009 who scored least marks in HSSC scored highest marks in MCAT. and in Part-I Examinations (p < 0.05). Linear regression on Part-I by taking HSSC and MCAT marks as independent variables showed that the MCAT marks exerted the greatest positive influence consistently at 0.104 (2008) and 0.106 (2009). In 2009 HSSC marks were shown to exert a negative influence (-0.08) on Part-I. CONCLUSION: There is need to standardise HSSC education and examination across all Intermediate Boards. MCAT is a better predictor of Medical Students' future performance.

The social mission of Australian medical schools in a time of expansion.

The social mission, or accepted social responsibility of Australian medical schools, was assessed at a time of rapid expansion and resulting pressure on staff and facilities. Nine new schools have been established in 2005-10 and there has been particular concern about adequacy of clinical training places. Discussions with most of the deans revealed their strong social commitments. We consider two of these in depth - raising the status and thus the involvement of students in general and especially rural practice; and increasing the numbers of Indigenous students and the knowledge of Indigenous health and culture among all students. We examine a system by which medical schools in the USA have been ranked for social mission achievements and suggest this approach might be used in Australia to measure the response of medical schools to Government initiatives and policies.

Evaluation techniques in Punjab, Pakistan: eight years of reforms in health professional education.

Pakistan, the most populated country in the WHO Eastern Mediterranean region has a population of over 170 million, spread over five provinces and four federally administered areas. It has a growth rate of 1.9%. Punjab is the most populous and developed province with an estimated population in 2010 of 81 million. In 2008, Punjab's development index of 0.60 and a literacy rate of 80% were the highest in the country. In Pakistan, the number of doctors and nurses has risen from 48 to 71 per 100,000 and from 16 to 30 per 100,000, respectively between 1990 and 2003. The major challenge, still, is the imbalance of the population to health-care workers ratio. At the time of creation of Pakistan, King Edward Medical College was the only fully functioning medical college. Over the years, as a result of health reform initiatives, a number of government medical colleges were established in the country. University of Health Sciences, Lahore was established in 2002, having sole jurisdiction over all medical, dental and allied health institutes in the province with the aim of moving medical education towards an outcome-based patient and community-oriented competency-driven system. This paper attempts to clarify how initiatives and reforms in the evaluation process have helped the UHS realise its aims. Evaluation in all branches of higher education has long been taken as a means to an end. The focus of UHS on teacher-training, introduction of behavioural sciences as a compulsory subject and setting up an outcome-based evaluation process, has established a knowledge-acquisition medical education atmosphere. The challenges in the future relate to sustainability through capacity-building and staying abreast with the Best Evidence Medical Education practices worldwide, implementing them to fit our local needs and resources.

Exploring Dimensions of Empowerment from the Patients' Perspective in One Specialist Epilepsy Service in Ireland.

Empowerment is integral to patient-centered practice, particularly as this relates to people with chronic conditions, though operationally it is poorly understood in this context. Empowerment, therefore, as experienced by patients with a chronic condition needs exploration. This article reports the experience of empowerment by patients in one specialist epilepsy service in Ireland as an exemplar of broader issues affecting empowerment of patients with chronic conditions. A Frameworks Approach was used to analyze in-depth interviews with patients (n = 10) in one Irish epilepsy service. Analysis was further informed by nonparticipatory observation of service delivery. Results indicate that patients' negative experiences of empowerment appear to be derived from traditional social norms relating to clinician patient power dimensions and social stigma internalized by clinicians at an unconscious level. With this in mind, educational approaches based upon critical social theory may provide a framework and guide to enable services to engage with these issues and embrace empowerment of patients with chronic conditions within therapeutic engagement.

Work-related stress and well-being of direct care workers in intellectual disability services: a scoping review of the literature.

Background: Understanding the nature of work-related stress and burnout among intellectual disability care staff is important to protect the well-being of these workers and encourage their retention in the sector. Though reviews of specific aspects of this literature have been conducted no article has sought to fully chart the range and nature of this research. Objective: This article addresses this gap by synthesizing the findings of such research with consideration to the future implications for protecting the well-being of care workers. Methods: A scoping review of the published literature was undertaken using a framework described in a previous article. Results: The findings of this review are presented thematically across six primary categories: challenging behavior; reciprocity; coping and stress; role issues; individual differences; and settings. A seventh theme, namely the positive aspects of intellectual disability care work was also identified through this process and is discussed. Conclusion: Occupational stress and strain is an internationally experienced issue in this sector. Challenging behavior and inequality in the relationships between staff and their clients, their colleagues, and their organization appear to exert a significant impact on the stress and well-being of workers in this sector. Excessive workplace demands, a low level of control, and a lack of support have been shown to be related to higher levels of stress and burnout among intellectual disability care workers.

Effects of peritoneal dialysis fluid biocompatibility on baroreflex sensitivity.

Conventional low biocompatibility peritoneal dialysis (PD) fluid composition has been driven by manufacturing expediency and cost limitations. PD is associated with significant acute changes in cardiovascular functional parameters, at least in part influenced by fluid composition. Short-term control of blood pressure (BP) is under control of the baroreflex arc. The aim of this study was to investigate the effects of PD fluid biocompatibility on baroreflex sensitivity (BRS). We studied 10 non-diabetic established continuous ambulatory PD patients, in a randomized crossover trial comparing conventional and biocompatible PD fluids. Systemic hemodynamics were continuously monitored using digital pulse-wave analysis. Plasma glucose and insulin were assessed during treatment with both 1.36% and 3.86% glucose-containing fluids. BRS was calculated offline from continuous BP and interbeat interval data. BRS was significantly higher with conventional PD fluid during both 1.36% (P<0.001) and 3.86% (P<0.001) dwells. Systolic BP was higher; heart rate, stroke volume, and cardiac output were lower; and total peripheral resistance increased during exposure to either fluid. There were significant differences between fluids with respect to the magnitude of these responses. Plasma glucose and insulin concentrations, and ultrafiltration volumes were significantly higher during the 3.86% dwell than the 1.36% dwell, but there were no differences between standard and biocompatible fluids. We have demonstrated for the first time that PD fluid biocompatibility rapidly affects BRS. These changes occur against a background of cardiovascular variability, hyperinsulinemia, and hyperglycemia. Further research is needed to explore the mechanism and, more importantly, the consequences of these findings.

Postgraduate medical training in Pakistan: observations and recommendations.

An appraisal of postgraduate training under the aegis of the Higher Education Commission in 2006-2007 showed strong input of supervisors and enthusiasm of trainees. Problems were evident however, beginning with the virtual absence of training for family doctors. Early moves in provision of this training are applauded. Greater undergraduate contact with primary care may help to raise its status but a trained workforce is necessary to make student placements practicable. Some uncertainties about specialist qualifications need to be resolved. Trainees' concerns focussed on the absence of stipend for many; inadequate supervision due in part to insufficient faculty; the poor condition and maintenance of some teaching hospitals; difficulties with aspects of College of Physicians and Surgeons processes; and the lack of career paths. All trainees should receive payment for their clinical duties and responsibilities; there should be a national review of faculty numbers; the management and suitability of hospital facilities should be examined. It is pleasing to know that problems at the College are being addressed; and the provision of career paths including post-fellowship experience should be a priority matter. Medical workforce planning is addressed and a call made for better data. Overcoming deficiencies will mean an increased budget for health, presently among the lowest in the region.

Critical realism: a philosophical framework for the study of gender and mental health.

This paper explores gender and mental health with particular reference to the emerging philosophical field of critical realism. This philosophy suggests a shared ontology and epistemology for the natural and social sciences. Until recently, most of the debate surrounding gender and mental health has been guided either implicitly or explicitly within a positivist or constructivist philosophy. With this in mind, key areas of critical realism are explored in relation to gender and mental health, and contrasted with the positions of positivism and constructivism. It is argued that critical realism offers an alternative philosophical framework for the exploration of gender issues within mental health care.
